Beleren (2015). A custom typeface for the trading card game Magic: The Gathering (Hasbro).

Uppercut Angle (2011). A signage typeface by Joachim Müller-Lancé. It was originally developed for the Krav Maga training center of San Francisco.

Ysobel (2009; winner of an award at TDC2 2010). Delve co-designed the newspaper type family Ysobel (Monotype) with type designers Robin Nicholas, head of type design at Monotype, and Alice Savoie (Frenchtype, Monotype). The sales pitch: According to Nicholas, the idea for the Ysobel typefaces started when he was asked to create a custom, updated version of the classic Century Schoolbook typeface, which was designed to be an extremely readable typeface - one that made its appearance in school textbooks beginning in the early 1900s.
